Video: Running PS4 via XBox One's HDMI Input Demonstration

To quote: You Can Play PS4 Through Xbox One, But You Probably Wouldn't Want To.

What happens when you plug a PlayStation 4's HDMI cable into the back of an Xbox One? The same thing that happens to everything else.

The fine folks at DigitalFoundry plugged their PlayStation 4 into the Xbox One's HDMI input and - contrary to my fevered speculation - a singularity was not formed. Instead, they got the PS4 video in their Xbox One dashboard.

From there they could navigate PlayStation menus, fiddle about with settings, or even launch a game, though lag issues make it a less-than-ideal means of doing so.
